Image registration has always been one of the most challenging works in image processing, especially for multi-source images. In order to achieve in-depth analysis, it is necessary to take advantage of the images obtained by different sensors [1]}, [2]}, [3]}, [4]}, and the accurate registration of these images is the fundamental premise. Multi-source image registration is an essential step to implement multi-source data fusion, multi-source collaborative classification, and joint analysis.
